Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a recording unit mounting structure of a facsimile apparatus that uses roll paper for recording paper.

[0002]

[Prior Art]

 In a popular facsimile machine that uses roll paper in which long thermal paper is wound around a paper tube, the recording paper fed from the roll paper stored in the recording paper storage section of the main body is guided to the recording section inside the main body. In many cases, the document is printed out, cut into a specified size, and then ejected outside the machine from the recording paper ejection opening on the back side of the main body.

In this type of facsimile machine, it is pointed out that when the recording paper tray is attached to the recording paper discharge port, the occupied space of the entire apparatus becomes extra by the protruding length of the tray. Therefore, as shown in FIG. 3, the recording paper P fed from the roll paper R stored in the recording paper storage unit 22 of the apparatus main body 21 is discharged backward from the recording paper discharge outlet 24 opened on the upper surface of the main body. As a result, there has been proposed a facsimile machine improved so that a recording paper tray (not shown) mounted in the recording paper discharge port 24 is less likely to protrude from the apparatus main body 21.

[0004]

[Problems to be solved by the device]

 However, in a model in which the recording paper P fed from the built-in roll paper is discharged from the upper surface of the main body, when the recording paper cover 23 mounted on the recording paper storage unit 22 is opened and the roll paper R is loaded or replaced. In addition, there is a drawback that the necessary initial set of the recording paper becomes very troublesome. Specifically, in this type of conventional product, as shown in FIG. 3, the components of the platen roller 25, the thermal head 26, and the auto cutters 27a and 27b, which constitute the recording unit, are located in front of the recording paper storage unit 22. Since the recording paper P is installed in the main body 21 of the apparatus, in order to set the recording paper P in a predetermined print standby state, the leading end of the recording paper pulled out from the roll paper R is inserted from the paper feed path 28 to the platen. This is because the operator is forced to perform a complicated manual work of passing the roller 25 and the thermal head 26, and further through the cutting positions of the cutters 27a and 27b and then leading them out to the recording paper discharge port 24.

The present invention eliminates such inconvenience, improves the initial setting of the leading edge of the recording paper to a simple one, and has the function of preventing the occurrence of paper jam due to the loosening of the recording paper when the cover is closed. It proposes a new recording part mounting structure.

[0006]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention covers a recording paper storage unit in a facsimile device in which a recording paper fed from a roll paper stored in the recording paper storage unit of the apparatus main body is discharged from the upper surface of the main body. The platen roller, thermal head, cutter and paper holder are attached to the inner surface of the upper cover.

[0007]

[Action]

 If the mounting structure of the recording unit is modified in this way, when the roll paper is replaced, the upper cover that covers the recording paper storage unit is opened, and the platen roller, thermal head, and cutter parts that are mounted on the inner surface of the unit cover together with the upper cover. It is possible to easily set the leading edge of the recording paper that is exposed above the recording paper storage unit and is pulled out from the storage roll paper in this state.

Further, when the upper cover is opened, at the same time, the paper holder is lifted in a horizontal posture on the recording paper storage portion, and the storage roll paper can be placed and set on the paper holder. This not only simplifies the setting of roll paper, but also prevents excessive slack in the recording paper during the process of closing the upper cover after setting the leading edge of the recording paper on the recording section inside the cover, It is possible to prevent the occurrence of paper jam due to the bending of the recording paper.

[0009]

EXAMPLES Examples will be described below with reference to the drawings.

1 and 2 illustrate an embodiment of the present invention. In the figure, 1 is a main body of the apparatus, 2 is a recording paper storage section (recording paper storage box) arranged in the rear part of the main body 1 of the apparatus, 3 is an upper part that covers the upper rear surface of the main body 1 of the apparatus including the recording paper storage section 2. A cover is attached to the apparatus body 1 so as to be openable and closable around a fulcrum O near the rear end.

The upper cover 3 has a recording paper discharge port 4 opened at an intermediate step portion thereof, and a platen roller 5, a thermal head 6 and an auto cutter 7a constituting a recording portion are formed on an inner surface of a front end portion of the upper cover 3. The respective components 7b are mounted in a predetermined positional relationship via a mounting member (not shown), and the recording paper P fed from the roll paper R stored in the recording paper storage unit 2 is transferred to the thermal head 6 against the platen roller 5. It is led out to the recording paper discharge port 4 through the press-contacting part and the cutting positions of the auto cutters 7a and 7b.

In the platen roller 5, the platen gear 5 a is meshed with an idler gear 8 arranged in the main body 1 of the apparatus with the upper cover 3 closed, and the platen roller 5 is driven by a motor 9 mounted in a front portion of the main body 1. It is designed to be rotationally driven via 8. The movable blades 7a of the automatic cutters 7a and 7b are driven by a dedicated small actuator (not shown) attached to the upper cover 3 together with the recording unit.

Further, a gutter-shaped paper holder 17 having a curved lower end is attached to the inner surface of the upper cover 3 together with the recording section. This paper holder 17 forms a rear wall portion of the recording paper storage unit 2 that enters the recording paper storage unit 2 and substantially stores the roll paper R when the upper cover 3 is closed as shown in FIG. On the other hand, in the open state of the upper cover 3 shown in FIG. 2, the upper cover 3 is lifted together with the cover 3 to take a horizontal posture on the recording paper storage unit 2, and the roll paper R is directly placed on the recording paper storage unit 2. It can be set.

In addition, 10 is an operation panel, 11 is a paper feed unit for a transmission document, 12 is a paper feed mechanism for a document, 13 is a document image reading mechanism, and 14 is a power supply unit. Reference numeral 15 denotes an original mount connected to the original feeding section 11, and 16 denotes a recording paper tray connected to the recording paper discharge port 4. In the recording paper tray 16, when the upper cover 3 is closed, the protruding length toward the back side of the main body is shortened. In the illustrated example, both the original mount 15 and the recording paper tray 16 are integrated with the upper cover 3.

The operation of the recording portion mounting structure described above is shown in FIG. That is, if the components such as the platen roller 5, the thermal head 6, and the auto-cutters 7a and 7b that conduct the recording paper P are attached to the inner surface of the upper cover 3 that covers the recording paper storage unit 2, when the upper cover 3 is opened, As shown in the figure, they are exposed above the recording paper storage unit 2 together with the upper cover 3, and the leading end of the recording paper set pulled out from the roll paper R newly stored in the recording paper storage unit 2 is set. Since it can be performed in the open space on the main body 1, the work is greatly simplified as compared with the case where the device is inserted into a narrow passage in the main body of the device and electrically connected.

Further, the paper holder 17 forming a part of the recording paper storage unit 2 is also attached to the upper cover 3, so that the roll paper R can be easily set, and the recording paper P when the cover is closed. It is possible to prevent the occurrence of paper jam due to slack.

That is, if the stored roll paper R is temporarily set in the recording paper storage unit 2 in advance and placed, the recording paper leading end pulled out from the roll paper R is set as a recording unit on the inner surface of the cover. Assuming that the initial setting of the recording paper P to be conducted is performed, when the upper cover 3 is closed and the printing standby state of FIG. 1 is restored, the recording unit on the cover side is a roll paper stored in the recording paper storage unit 2. When the recording paper P pulled out from the roll paper R is inevitably loosened due to the displacement from the separated position from the R to the close position, the recording paper P may be irregularly bent to cause a paper jam.

On the other hand, as shown in FIG. 2, when the roll paper R is placed on the paper holder 17 attached to the upper cover 3 and the initial setting of the leading edge of the recording paper is performed, the upper cover 3 is set after the setting. In the process of closing to the print standby state, the recording unit and the storage roll paper R supported by the paper holder 17 pivot about the concentric O, and the length of the recording paper P drawn from the roll paper R to the platen roller 5 is extended. Does not occur, and therefore the recording paper P is not excessively loosened. Therefore, the cause of the paper jam caused by the irregular bending of the recording paper P that is loosened when the cover is closed can be accurately removed.

[0019]

[Effect of the device]

 As described above in detail, in the recording unit mounting structure of the present invention, the platen roller, the thermal head, and the cutter are mounted on the inner surface of the upper cover that covers the recording paper storage unit. Eliminates the annoyance of initial setting at the beginning of the recording paper when replacing the roll paper, which has been a problem in the past with a fax machine of a model that ejects the recording paper delivered from the roll paper stored inside the main body. can do. Further, since the paper holder is also attached to the inner surface of the upper cover, it is possible to prevent the occurrence of the paper jam due to the looseness of the recording paper when the cover is closed.
